Questions
  1. On your own paper, use the graph to find the number of grams of sugar that will dissolve in 100 grams of water at 80ºC
  2. How many grams of sugar would dissolve in 200 grams of water at 80ºC?
  3. Use the graph to find the temperature, in Celsius, that will dissolve 300 g of sugar in 100 g of water.
  4. What is the dependent variable in the graph shown? (Dependent variables are always on the Y-Axis)
  5. What is the independent variable in the graph shown? (This is what you can control, and also always on the X-Axis)
  6. What are line graphs used for
    • a) Express percentage
    • b) Compare sets of data
    • c) Show change over time or against another variable
Instructions
  1. Collect Data
    1. Choose a partner (one will do jumping jacks, the other will time)
    2. Use the stopwatch at http://www.online-stopwatch.com/ to time your partner doing 20 jumping jacks (or pushups if you think you can handle it)
    3. Complete 5 trials. (10 if you can handle it!)
    4. Both people do their own graph from the one person's data.
  2. Make a Line Graph
    1. Make graph paper with a ruler and notebook paper
    2. The graph must take up most to all of the paper
    3. Figure out a scale that will cover the paper (each box is worth ?)
    4. Use colored pencil on the line and titles
    5. Label the x axis trial number
    6. Label the y axis time for 20 jumping jacks (s)
  3. Staple all three graphs together and turn them in. Due today.
